I think
The Newbridgctionary, compiled by buffcoat, is the closest thing to what you're describing. Having assisted with some official Show compilation projects, I feel pretty confident in saying that it is pretty well definitive for Newbridge Calls from the start of the show through the end of "volume one" in 2013. I don't recall ever running into any appearances that weren't covered there or not being able to find something by cross-referencing buffcoat's list/Omar's recaps/the forum/my own notes.
I think there are a few other pretty in-depth lists that have been compiled by Users of a Certain Era as well, but I'm not sure if they're available or still up anywhere. At one point, I think around the 10th anniversary, I put together a list of how many calls and different characters and appearances by those characters by Jon, but that would be pretty out of date by now if I still have it. I had a pretty thorough call-for-call history of Bryce and Philly Boy Roy as research for the box set as well, detailing the their evolution and the first appearances of their character traits.
There have been a few attempts at rockin' a wiki over the years, but none have really come together. Some are still around in some form, and I think there's even still some pre-Newbridge era stuff around. As far as what's available online, I think a combination of the Newbridgctionary list and
Omar's recaps are probably as close as you can get for an exhaustive character guide that covers several years.
